An airlock door in the side of the Satona had opened. Grotesque in their goggled, billowing space suits three Martians were coming down a swinging ladder. The weight of the Wanderer, still clamped against her shell, was holding the larger craft askew. Not great, this weight, it is true, for the gravity of the miniature world was exceedingly minute, but the Martian captain had evidently thought it not worth while to correct the canting by use of his power-exhausts.

Arnim and Britt watched the ten-foot-tall aliens stride across the short stretch of deck to the entrance back of their own vessel. Around the waist of each a studded belt was clamped, its excrescences showing where the individual gravity coils were inserted. Were it not for these the Martians would have been rising a hundred feet with each step, so small was the asteroid's attraction.

Compare to the anti-gravity belt from Philip Frances Nowlan's 1928 story Armageddon: 2419 A.D., the gravity web from Frank Herbert's 1969 novel Whipping Star and synthetigrav from James Schmitz' 1949 story Agent of Vega.
